A By

.l is represented in the a which 'similar ASf-.FATES ATENT onirica."

of'Corvallis,'in the county of Benton and.

State of Oregon, have invented a new and Improved ReversingGear, ofwhich the following -is a full, clear, and exact description.

The object of the invention is toprovide a -new and improved reversinggear for traction engines and other power.vehicles, and arranged topermit convenient and quick reversing for driving the vehicle in thedesired direction.

The invention consists of novel features and-parts and combinations' ofthe same, which will be more fully described hereinafter-andthen ointedout in the claims.

. practical3 embodiment of the invention companying drawings forming apart of this specification, in

c aracters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional side elevation of part of a` motor vehicle,provided with the improvement, the section being on the line 1-1 ofFig.. 2; Fig. 2 is a plan view of'the same; Fig. 3 is a cross section ofthe same; Fig. 4 is a side elevation of part of the reversin gear, andFig. 5 is a transverse section o the improvement on the line 5-5 of Fig:1.

he sprocket chain A is driven from an .engine or other motor mounted onthe frame B of the vehicle, and the said sprocket chain.

A passes over a sprocket wheel C, secured on a transversely-extendingshaft D, journaled in suitable bearings, held on a lever E, fulcrumed atE on a bracket B attached to the main frame B of the vehicle. The leverE is ivotally connected by a link F with. a sli e G, mounted to slide onthe bracket B and pivotally connected by a link H with a hand lever Iunder the control of the operator, and ulcrumed at I on a bracket B2,attached to the main frame B. The hand lever I- is adapted to be lockedto a quadrant J. soasto hold he lever E ina desired position, ashereinafter more fully enplained.

yOn the shaft D is secured a pinion K in meshwith a pinion K journaledon the lever E, in such a manner that the two pinions K and K arelocated on opposite sides of the ulcrum E of the lever E (see Fig. 4).y

Either of the pinions K, K is adapted to be moved in mesh with acompensating ear.

swinging motion to the lever E, by manipulating the lever I; that is,when the lever I is in the position shown in Fig. l, the pinion K is inmesh with the gear wheel L, while the pinion K is out of mesh with thesaid gear wheel L, and when' the lever I is shifted, to swing the leverE into the -position shown in Fig. 4;, then the pinion K is outV of meshwith the gear wheel L, and the pinion K is in mesh with the said gearwheel.

It is expressly understood that no matter what position the lever E maytake as described, the pinions K and K are in mesh with each other andare rotated simultaneously whenever a traveling motion is given to thesprocket chain A by the motor of the ve icle. l

, he compensating gear wheel L Aisniounted to rotate loosely on the hubof a bevel gear wheel N, secured on a shaft O, journaled in suit-ablebearings on the 'frame B, and extendingtransversely thereon. On the webof the gear wheel L are journaled beveled inions L in mesh'with thebevel gear wheel IN above mentioned, and also in mesh with aV bevel gearwheel P, mounted to rotate loosely on the shaft O. The bevel gear wheelsN and P are located on opposite sides of the gear wheel L, and the bevelear wheel P is provided with a pinion P in mesh with a gear wheel Q,attached to one of the traction wheels R, the other traction wheel R',having a similar gear wheel Q in mesh with a pinion O similar to thepinion P and 'secured on the shaft O.

When the several parts are in the position illustrated in Fig. l and atraveling motion is given by the motor to the sprocket chain A, then thepinions K and K are driven, and as the inion K is in mesh with the gearwheel L, t e latter is rotated in the direction of the arrow b, wherebya rotary motion is transmitted to the traction wheels R, R in thedirection of the arrow o', to propel the vehicle forward in thedirection of the arrow al.

When the lever E is shifted by the' operator manipulating the lever I,to the position shown in Fig. 4f, then the gear wheel L is turned in theopposite direction of the arrow b', to cause the rotation of thetraction wheels R, R in the opposite direction o the arrow c', to propelthe vehicle backward, that is, in the opposite direction of the arrow d.

From the foregoing it will be seen that the v Patent:

operator by simply manipulating the hand lever I, can convenientlyreverse the travel of the vehicle Without stopping -or reversing themotor. i

. Thecompensating gearing described, and consisting essentially of thebevel gear Wheels N, P, permits the traction Wheels R, R to turn atdiiierentiahspeed when going around a curve or the like.

By the arrangement described, the draft of .the traction wheels iseqnali'zed, to allow each traction 'wheel to. turn a' short curve.

with equal power. The device may be used for other purposes.

The dvice is very'simple, dnrablein construction and composed ofcomparatively few AAerts, not liable easily to get out of order,

Having thus described 'my invention, I claim' as new and desire tosecure by Letters l. A reversing gear for traction engines and otherpower vehicles, comprising a lever, pinions journaled on the said leverone at each side of its pivot and in mesh. with each other, one of thepinions being driven, a

compensating gear Wheel 'adapted to be engaged by either of the saidpinions, the said gear Wheel being geared with the traction Wheels, alink connected v'lth one end ofthe said lever, a slide connected withthe said link, a, hand lever, Vand e link connecting the said hand leverWith the sind slide.

2. A reversing gear for traction engines and other power vehicles,comprising a lever,

pinions jonrnaled on the said lever'ene at each side of its pivot and inmesh with each other, one ot' the pinions being driven, a compensatinggear Wheel adapted to be engaged by either of tbe seid pinions, the saidgear Wheel being geared with thel traction Wheels, a link connected withone end of the seid lever, 'e slide connected with the said link, a handlever, a link connecting the said hand lever With the said slide, and aquadrant for engagement by the said hand lever ,to look the letter inplace.

In a reversing gear for traction engines and other vehicles, a. freine,traction Wheels mounted in the freine, a bracket carried by thel frame,a lever pivoted to the bracket, pinions mounted on the lever one at eachside of its pivot and meshing with each other, ineens for operating oneof said pinions, ay slide mounted bn the bracket-,a link connecting theslide with one end of the lever, an'operating lever, e link connectingthe operating lever with the slide, a'gear Wheel With which the epinionsare adapted to alternately engage, and means for oper- .ating thetraction Wheels from said .gear
